- Adapt SetWindowResourceText() function from
`msconfig_new/utils.c` LoadResourceStringEx() function.
- Drop `version.rc` in favor of `uxtheme.rc` since we have forked uxtheme.
Addendum to 118869f69. CORE-5991
This is prerequisite to supporting Vista+ iteration of the msstyles format,
and also for implementing GetThemeStream() later.
Visual styles compiled for Vista+ can now use PNG images in the IMAGE group.
This does not affect the ability to use BMP images, they can be mixed now.
